| Abstract: | Abstract: Laparoscopic microwave coagulation (LMC) has recently been indicated for hepatocellular carcinoma (HCC). LMC was performed in 14 patients with a total of 22 HCCs in the 18-month period from November 1996 to April 1998. The size of HCCs ranged from 10 mm to 100 mm, with an average diameter of 29.3 mm. The duration of microwave emission ranged from 8 min to 54 min; average 26.4 mm. Sufficient microwave emission was possible even in cases of multiple HCC large HCC, and HCC located deep within the liver, with the aid of laparoscopy and intraperitoneal ultrasound. Recurrence was observed in 4 out of 22 HCCs, and was treated by transcatheter arterial embolization (TAE) or percutaneous ethanol injection (PEI). LMC facilitates local control of HCC, and is a promising new therapeutic modality for HCC. (Dig Endosc 1999; 11: 137–143) |
